JACOB HITZERT, OF ONAWAY, MICHIGAN.

CLEVIS.

To all whom it may concern:

Be it known that I, JACOB HITZERT, citizen of the United States,residing. at Onaway, in the county of Presque Isle and State ofMichigan, have invented new and useful Improvements in Clevises, ofwhich the following is a specification.

My present invention pertains to clevises, and consists in the strong,safe and easily opened clevis hereinafter described and particularlypointed out in the claims appended.

In the drawings, accompanying and forming part of this specification:Figure 1 is a perspective view showing the clevis constituting the bestpractical embodiment of my invention that I have as yet devised as thesame appears when closed. Fig. 2 is a plan view showing the clevis asopen. Fig. 3 is an enlarged detail perspective view illustrating thepreferred hinge connection between the major members of the clevis. Fig.A is a fragmentary view, partly in elevation and partly in section,showing the manner in which the ring or minor member of the clevis isretained on the upstanding end portion of one major member by the swellof the latter.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A and B are the major members of my novel clevis, and G is the ring orminor member.

The major member A is of general rightangle form, and comprises ahorizontal arm or, having a bifurcated and apertured portion 6 at itsinner end, and'an upright arm or portion 0 which rises from the oppositeor outer end of arm a and is provided on its rear side, adjacent itsupper end, with a swell cl, best shown in Fig. 4. I would also have ithere understood that I prefer to make the arm 0 of circular form incrosssection so that it can be pivoted in a device to be drawn, and thatI also prefer to provide said arm near its upper end with a v transverseaperture 6, the latter to receive a retaining pin (not shown) when it isdeemed necessary or desirable to employ the same.

The major member B is of general U- shape, and has a lower comparativelyshort arm f, an upper arm 9 which terminates at its rear end in an eyeit, and a forward big'ht i, the latter for the connection of a draftappliance. As will be noted by comparison of Specification of LettersPatent. Patented June 14,. 1910, Application filed February 18, 1910.

Serial No. 544,597.

Figs. 1 and 2 the sides of the bifurcated por- 'pivotally connected tothe sides of the portion Z); the pivotal connection being effectedthrough the medium of a rivet D the ends of which are countersunk in thesides of the bifurcated portion 6 as best shown in Fig. 3.

It will also be noted that the sides of the bifurcated portion 6 and theterminal j are of general circular form, and that the hinge connectiondescribed is, as a whole, strong and durable and well adapted towithstand the strains placed upon it.

The ring or minor member C of the clevis is pivoted in the eye it ofmajor member B, and is therefore adapted to be swung on and ofi theupstanding arm 0 of major member B. Said ring C is also adapted to bepressed down over the swell d and retained against casual upwardmovement by the same. When, however, the ring 0 is crowded upward pastthe swell ol, the member B is re leased from the upstanding arm ofmember A, and may then be swung to a position at right angles to memberA, as shown in Fig. 2, to permit of the ready connection of a draftappliance (not shown). Then after the connection of the draft appliance,the member B may be restored to the working position shown in Fig. 1 andretained in such position by the engagement of the ring C with the arm 0of member A.

While I have shown and described one form of my invention, it is to beunderstood that I am not limited to the details or the form or relativearrangement of parts disclosed, but that modifications may be madetherein, without departing from the spirit thereof.

Having described my invention, what I claim and desire to secure byLetters-Patent, 1s:

1. The combination in a clevis, of a major member, of generalright-angle form, having a horizontal arm the inner portion of which isincreased in width and bifurcated, and also having an upstanding arm, ofcircular form in cross-section, and a swell on the rear side of said armadjacent the upper end thereof; a major member, of general U-form,having a comparatively short lower arm and a wide terminal thereoninterposed between and pivoted to the sides of the said bifurcatedportion, and also having a forward bight and an upper arm whichterminates at its rear end in a horizontallydisposed eye; and a ringpivoted in said eye and movable on and off the upright arm of theiangular member, substantially as speci- 2. The combination in a clevis,of a major member, of general right-angle form, having a horizontal armand also having a rear upstanding arm and a swell on the rear side ofsaid arm adjacent the upper end thereof; a major member, of generalU-form, having a lower arm hinged to the horizontal arm of thefirst-named member and also having a forward bight and an upper arm, anda ring pivoted to said upper arm and movable on and off the upright armof the firstnamed member.

3. The combination in a clevis, of a major member, of generalright-angle form, having a horizontal arm and also having a rearupstanding arm on said horizontal arm; a major member, of generalU-form, having a lower arm connected by a vertical hinge to thehorizontal arm of the first major member, whereby the second majormember is enabled to swing horizontally on the first major member, andalso having a forward bight and an upper arm; and a ring pivoted to saidupper arm and movable vertically on and off the upright arm of the firstmajor member.

4:. The combination in a clevis, of a major member having an upstandingarm and also having an arm that reaches forwardly from said upstandingarm; a major member connected by a vertical hinge to the forward end ofthe forwardly reaching arm of the first major member, whereby the secondmajor member is enabled to swing horizontally on the first major member,and also having a forward bight and an upper arm directed rearwardlyfrom said bight; and detachable connecting means pivoted to said upperarm and movable vertically on and off the upstanding arm of the firstmajor member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JACOB HITZERT.
